针对非等模数非等压力角行星齿轮传动系统,建立了多自由度平移-扭转振动的非线性动力学模型。考虑到齿轮副齿侧间隙、系统综合误差和齿轮副模数与压力角的不相等,计算了系统的均载系数并对由它们所引起的系统不均载特性进行了动力学分析。获得了误差一定且齿侧间隙改变时,啮合副的动载荷曲线与均载系数间的变化关系。讨论了齿轮副模数和压力角分别不同时,系统均载系数的变化幅度。研究表明:随着齿轮副压力角选择范围的扩大,系统均载系数有着较大幅度的变化;齿侧间隙使系统的啮合副处于不同冲击状态,不同冲击状态对系统的均载性能有着重要的影响。
針對非等模數非等壓力角行星齒輪傳動繫統,建立瞭多自由度平移-扭轉振動的非線性動力學模型。攷慮到齒輪副齒側間隙、繫統綜閤誤差和齒輪副模數與壓力角的不相等,計算瞭繫統的均載繫數併對由它們所引起的繫統不均載特性進行瞭動力學分析。穫得瞭誤差一定且齒側間隙改變時,齧閤副的動載荷麯線與均載繫數間的變化關繫。討論瞭齒輪副模數和壓力角分彆不同時,繫統均載繫數的變化幅度。研究錶明:隨著齒輪副壓力角選擇範圍的擴大,繫統均載繫數有著較大幅度的變化;齒側間隙使繫統的齧閤副處于不同遲擊狀態,不同遲擊狀態對繫統的均載性能有著重要的影響。

A translation-torsion coupled nonlinear dynamic model with multi-DOF was established for a planetary gear train system with non-equivalent modulus and pressure angle.Considering backlashes,system's comprehensive errors and non-equivalent modulus and pressure angle of gear pair,the load sharing coefficient of the system was calculated.The dynamic characteristics of load sharing caused by the factors mentioned above were analyzed.Some relations between the dynamic load curve of gear pair and the load sharing coefficient were obtained due to certain errors and changes of backlash.The change range of the system load sharing coefficient was discussed with the variation of gear modulus and pressure angle.The results showed that the load sharing coefficient has a larger variation with increase in selecting range of pressure angle of gear pair,and the different impacts of meshing pair caused by backlashes have important influences on the load sharing characteristics of the planetary gear train system.
